  1. What is the mechanism of maintaining:
    1. Mean arterial blood pressure?
    2. Blood flow to specific organs?
    • 1. Neural (reflex) control
    • 2. Local control
  2. Define pressure storage
    • Ability of aorta and large arteries to expand during systole
    • Squeeze back during diastole
    • Maintain pressure
  3. Anchoring the heart:
    1. Vertically
    2. Horizontally
    • 1. Anulus
    • 2. Anular ring
  4. Calculate Total Peripheral Resistance
    (Mean arterial pressure - right atrial pressure) / Cardiac output
  5. Calculate Pulmonary vascular resistance
    (mean pulmonary arterial pressure - left atrial pressure) / cardiac output
  6. Where is peripheral resistance the highest? Why?
    • Arterioles
    • Small lumen, high wall thickness
  7. What fraction of blood is stored in the veins under resting conditions?
    2/3 - 3/4
